By using Selenium we can only do the Web app testing. But by using Katalon Studio, we can do Web app testing, Mobile App Testing and API Testing. In Katalon Studio, we can do the Cross Browser testing.

Katalon Studio is an automated testing platform that offers a comprehensive set of features to implement full automated testing solutions for mobile and Web applications. Built on top of the open-source Selenium and Appium frameworks, Katalon Studio allows teams to get started with test automation quickly by reducing the effort and expertise required for learning and integrating these frameworks for automated testing needs.

Selenium is perhaps the most popular automation framework that consists of many tools and plugins for Web application testing. Selenium is known for its powerful capability to support performance testing of Web applications. Selenium is a popular choice in the open-source test automation space, partly due to its large and active development and user community.

Strengths and weaknesses

The comparison table above mainly focuses on the common features of an automated testing tool. The following presents another perspective by picking and comparing key strengths and limitations of the tools.

Tools

Strengths

Limitations

Katalon Studio

No licensing and maintenance fees required (paid dedicated support services is available if needed).

Integrating necessary frameworks and features for quick test cases creation and execution.

Built on top of the Selenium framework but eliminating the need for advanced programming skills required for Selenium.

Emerging solution with a quickly growing community.

The feature set is still evolving.

Lack of choices for scripting languages: only Java/Groovy is supported.

Selenium

Open source, no licensing and maintenance fees.

Large and active development and user community to keep pace with software technologies.

Open for integration with other tools and frameworks to enhance its capability

Testing teams need to have good programming skills and experience to set up and integrate Selenium with other tools and frameworks.

New teams need to invest time upfront for setup and integration.

Slow support from the community.

There is no one-size-fits-all tool for automated testing. It is highly recommended that testers evaluate various tools in order to select what would best meet their automated testing needs. Programming languages and technologies used to develop software continue to evolve, as do the automated testing tools, making cost a significant factor in tool selection. Commercial vendors often charge for tool upgrades, which can be substantial if your software uses emerging and frequently changing technologies. Open source and non-commercial tools, on the other hand, do not incur additional charges but require effort and expertise for integrating new upgrades. It is difficult to find the support and expertise needed for integrating various tools and frameworks into open-source solutions. Emerging tools that integrate with open-source frameworks, like Katalon, offer a viable alternative to both commercial and open-source automated testing solutions
